The PS family of UPS (Uninterruptible Power Supply), is a line interactive device with
features conceived to provide an excellent protection to computers (PC), networks,
workstations and small capacity internet devices.

conditions under varations of the main power, without the need to get into battery or
backed up mode. This features results in in extended battery life.
The family uses a RISC (Reduced Instruction Set Computer), that provides greater
operational flexibility: 1) "Delayed turn on". During the turn on process the microprocessor
analizes the main power in order to ensure that it is in adequate conditions for the unit to
operate. 2) Green Power function. 3) "Overload Detection" and desactivation of the load if
the overload persists during a predetermined time. Additionally, the PS family has surge
protection, nosie filtering and fax/modem protection.
